Subject: [PATCH] Fix a typo in clean() warning
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The tests show:

t/builder-extra-dir.t .. ok
Use of uninitialized value $1 in concatenation (.) or string at /home/test/fedora/perl-Test-Directory/Test-Directory-0.051/blib/lib/Test/Directory.pm line 128.
test-directory-tmp-gRcbe:  at t/builder.t line 54.

This is because a typo in clean() method. A failed rmdir function sets
$! variable, but a croak call interpolates $1 variable that is usually
undefined at that time.

This patch fixes it.
